All ICE liquids have been formulated first in the UK using only the finest ingredients. Our nicotine base is formulated by highly trained chemists in our FDA Registered laboratory to the highest degree of accuracy. Unlike many other "Backroom Made" e-liquid companies who simply add flavoring to a Chinese made nicotine base, ICE liquids are created from scratch to current Good Manufacturing PractICEs (cGMP) in our French laboratory. All ICE bottles are also labelled with standard safety warnings, nicotine concentration, "best by" date, and a unique Lot Code indicating the batch from which the liquid was derived.
